APPENDIX. 313 



Calosoma black, short, broad, thick, dull. Head and 

 thorax very finely and thickly punctured. Head in 

 front, with an almost smooth disc, and a retuse and 

 excavated border on each side. Thorax slightly convex 

 and retuse along each side, narrower hindward, with a 

 slight impressed middle line. Elytra very convex on 

 each side ; each with about seventeen lines of minute 

 pustules. Length of the body, 8 lines. 



It is somewhat allied to an undescribed Callisthenes 

 from California, but is quite distinct. 



Genus CARABUS. (Linn.) 

 Carabus bicolor. N. S. 



Niger, breviusculus, subtilissime punctatus ; thorace 

 stria media bene determinata; lateribus subconvexis, 

 angulis posticis productis ; elytris cupreis lineis sex e 

 pustulis elongatis nigris ; lateribus subconvexus. 



Black, rather short. Head and thorax very minutely 

 punctured, the former with the usual impression on 

 each side in front. Thorax with an impressed distinctly 

 marked middle line ; sides slightly convex ; hind angles 

 produced, extending over the fore border of the elytra. 

 Elytra cupreous; each with three lines of elongated 

 black pustules, and with a submarginal line of minute 

 impressions ; sides slightly convex. Length of the body, 

 8 lines. 



This belongs to the group of C. ligatus and of C. 

 Mceander, which it resembles in the sculpture of the 

 elytra.
